BOLSTER.

Specification of Letters Patent.

Patented Sept. 12, 1905.

Application filed November 28, 1903. Serial No. 183,067.

To all. whom it may concern:

Be it known that I, EDWIN HnNDaY BEN- NERs, a resident of Elizabeth, in the county of Union and State of New Jersey, have i11- vented certain new and useful Improvements in Bolsters, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper tainsto make and use the same.

illy invention relates to an improved truckbolster, the object of the invention being to provide a cast-steel bolster which will embody maximum strength with minimum 1 weight 5 and it consists in certain novel features of construction and combinations and arrangements of arts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a top plan view illustrating my improvements. Fig. 2 is a view in side elevation; and Figs. 3, 4, and are views on the lines 1/y, and z 2, respectively, of Fig. 1.

My improved bolster consists of one integral casting forming in the main top member ".2, horizontal throughout the greater portieri of its length, bott-om member 3, of less width than top plate 2 and inelining or curving upward from its center to its ends and connected with top plate 2 by inclined o enwork webs 4, the cross-section of the bo ster thus being tapering from its top to its bottoni. The top and bottom lates 2 3 and side webs 4 all merge into sightly-enlarged bolster ends, having recesses or pockets 5 in their opposite sides for the column-bearings, the upper plate having recesses or cut-out portions 6 in its ends and the lower plate made with longitudinal and lateral strengthening-ribs 7 The top plate 2 has a raised ring or center bearing 8 and end bearings 9, and a hollow bearing-post 10 is made integral with top late 2 and is located in the center of center bearing S.

By constructing my improvements as above explained the tapering formation of Afrom my invention.

the bolster in cross-section, as seen most clearly in the sectional views, gives to the bolster great strength and durability to withstand all strains thereon at the same time having the bolster of minimum weight and neat and attractive in a pearance.

Vhile I have describen the side connecting webs 4 as inclined, as a matter of fact the upper portions of said side webs, which form, 1n effect, depending aprons .l1 from the side edges of top plate ".2, are disposed vertically and arc of greater thickness than the main or larger ortions of said side webs, and while I prefer this particular construction of bolster a great many changes might be made in the general form and arrangement of the several parts without departing .Hence I do not restrict myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the s irit and scope of my invention.

Having fu ly described my invention, what I claim as new, and desire to secure by Letters Patent, is-d 1. A bolster comprising a top plate, a narrower bottom plate and inclined side webs connecting them, said side webs being approximately straight from the top to the bottoni plates.

2.k A bolster comprising a top plate, a narrower bottoni plate and inclined open-work webs connecting said plates, said webs being approximately straight from the top to the bottom plates.

3. A cast-metal bolster, comprising a top plate, a bottom plate of less width than the top plate, and approximately straight side webs connecting the longitiuilinal edges of the top and bottoni plates..

In testimony whereof l have signed this specification in the presence of two subscribing witnesses.
